RegionInfo Constructor (Int32)

Initializes a new instance of the RegionInfo class based on the country/region associated with the specified culture identifier.

Namespace:  System.Globalization
Assembly:  mscorlib (in mscorlib.dll)

public RegionInfo(
	int culture
)

Parameters

culture
Type: System.Int32
A culture identifier.

ExceptionCondition
ArgumentException

culture specifies either an invariant, custom, or neutral culture.

RegionInfo.RegionInfo(String) is the recommended constructor for instantiating a RegionInfo object. Unlike the RegionInfo.RegionInfo(Int32) constructor that requires a numeric culture identifier as a parameter, its parameter is a more readable culture name or country code.

The culture identifier is mapped to the corresponding National Language Support (NLS) locale identifier. Detailed culture information is defined in the NLS information page at the Go Global Developer Centerhttp://msdn.microsoft.com/en-us/goglobal/bb896001.aspx.

The name of the new RegionInfo object is the ISO 3166 2-letter code for the country/region, not the 2-letter language and country/region codes. For example, the culture identifier 0x0409 for the English (United States) culture yields a country/region name of "US" instead of the culture name en-US.

The following code example compares two instances of RegionInfo that were created differently.


using System;
using System.Globalization;

public class SamplesRegionInfo  {

   public static void Main()  {

      // Creates a RegionInfo using the ISO 3166 two-letter code.
      RegionInfo myRI1 = new RegionInfo( "US" );

      // Creates a RegionInfo using a CultureInfo.LCID.
      RegionInfo myRI2 = new RegionInfo( new CultureInfo("en-US",false).LCID );

      // Compares the two instances.
      if ( myRI1.Equals( myRI2 ) )
         Console.WriteLine( "The two RegionInfo instances are equal." );
      else
         Console.WriteLine( "The two RegionInfo instances are NOT equal." );

   }

}

/*
This code produces the following output.

The two RegionInfo instances are equal.
